Appiieation mea June s, 1917. serial No. 173,568.

T0 all whom t may concern:

Be it known that I, FRANCIS J. S'rEU'rnR- MANN, a citizen of the United States, residing at Webster, in the countyl of Worcester and State of Massachusetts, have invented a new and useful Funnel, of which the following is a specification.

It is the object ofthis invention to provide novel means whereby "hot water may be directed to both sides of a carbureter on an internal combustion engine, for the purpose of warming the'air before the air enters the carbureter, and for the purposeI of warming the miXture after the mixture leaves the carbureter," and as the mixture proceeds to the intake manifold.

Itis wit-hin the province of the disclosure to improve generally and to enhance the utility of devicesof that type to which the present invention appertains. A l

With the above and other objects in view which will appear as the description proceeds, the nventionreside's- 'in the combination and arrangement of parts and in the details'o'f construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings l Figure 1 shows in side elevation, an internal combustion engine whereunto the device forming the subject matter of this application has been applied, the showing of the engine being largely diagrammatic;

Fig. 2 is a longitudinal section taken through the jacket which coperates with the air intake of the carbureter;

Fig. 3 is a fragmental vertical section taken through the supply funnel; and

Fig 4 is a top plan of the supporting arm of the funnel, a portion of the funnel appearing in section.

rl`he numeral 1 denotes generally an internal combustion engine comprising cylinders 2 and a carbureter 3, the intake manin fold appearing at 4 and the numeral 5 denoting a pipe leading from the carbureter to the manifold. The carbureter 3 comprises an air intake 6 and a fuel inlet 7.

In carrying out the presentl invention there is provided an arm 8 supplied at one end with an opening 9 adapted to receive one of the studs 10 commonly constituting a' part of an internal combustion engine and located on the cylinders 2 thereof. A nut 11 is threaded onto the stud 10 and engages `the arm 8 to hold the same inhorizontal outstanding position with respect to the cylinders of the engine. Adjacent its outer end, the arm 8 is supplied with an opening 12 in which is supported a receptacle 14, preferably in the form of a funnel.

The funnel 14 is providedv at yits lower end with a nipple 15 Vonto which is threaded `a cap 16. The lupper end of a primary tube 17 passes through the bottom of the cap 16 and is provided with anenlarged vshoulder 19 bound between the end of the cap-16 .and the end of the nipple 15. The lower end of the primary tube 17 dischargesas shown at 18 against theoutside of the pipe 5 which leads from the carbureter 3 to the manifold 4. Since the shoulder 19 is bound between the end of the cap 16y and the end of the nipple 15, the tube 17 may be adjusted circumferentially, so that itsllower end will be located 'properly with respectto the pipe 5.

In the lside of the funnel 14 ,near to its lower end is mounted a nipple 2O onto which isl threaded a cap 21. A secondary tube 22, which may.y be flexible if desired, passes through the cap 2l and has a shoulder 23 bound between the end of the cap and the end of the nipple 20 so that the tube 24 may be adjusted circumferentially, thereby to change the location of a jacket 24 (hereinafter described) which is mounted on the lower end of the tube 22.

As aforesaid, the numeral 24 marks a jacket of tubular form and comprising an inner wall 25 and an outer wall 26 spaced apart at their ends by rings 27. Solder indicated at 28 may be inserted between the walls 25 and 26 of the jacket 24 at the ends of the said walls and outwardly of the rings 27. It is to be understood, however, that the specific method of building up the jacket 24, above described, is not insisted upon. Between the walls 25 and 26 of the jacket 24 there exists a water space 29. The outer wall 26 of the jacket 24 is provided at Aits top, or elsewhere, with a nipple 31, connected with the lower end of the secondary tube 22. In the outer wall 26 of the jacket 24, at the bottom of the jacket, there is formed a water outlet 30.

The jacket 24 is slipped over the end of the air intake 6, as indicated in Fig. 2. In order to hold the jacket 24 on the intake 6, one end of a retractile spring 32 is engaged around the nipple 31, and the other end of the spring is assembled with any'accessible projection 33 on the manifold, or. with any other projection about the engine which is so disposed that the spring may be connected therewith.

`In practical operation, a quantity of hot of the jacket flowsslowly away through the opening 30. v e v It is obvious that the tube 22 and the jacket 2.4 constitute the means whereby the air will be warmed before it enters the manifold 3, the tube 17 constituting means wherebythe mixture proceeding from the manifoldk 3 will be warmed, further, before it 1. enters the manifold 4.

Having thus described the invention, what is claimed is l. The combination with an internal combustion engine comprising a carbureter having an air inlet, of a jacket assembled with the inlet and provided with an outlet; a hot walter receptacle; a tube leading from the receptacle to the jacket; and spring means for holding thejacket on the inlet.

v 2. In a device of the class described, an internal combustion engine comprising a carbureter having'anair inlet and a mixture conduit leading from the carbureter; an arm mounted on the engine; a funnel supported in the arm; tubes rotatably connected with the funnel, one tube discharging on the mixture conduit; and a jacket mounted on the air inlet, the other tube communicatin with theljacket. y

, 3. device constructed in accordance with claim 2, with a retractile spring extended between thecarbureter and the jacket and constituting means for holding the jacket on the air inlet.

4. The combination with an internal combustion engine comprising a carbureter and an intake member leading therefrom, of a receptacle independent of the cooling system of theengine, and into which `water may be poured, and two open, independent conduits leading from the spaced portions of the receptacle and discharging, respectively,

upon a part of the carbureter and upon the y y intake member.

In ltestimony that Iv claim the foregoing as my own, I have hereto affixed my signature in the presence ofl two witnesses.
